The family of a shepherd from the Caucuses inherits a car-wash in Moscow. From the far-away pastures they come to the capital and find themselves in an entirely different world with different values. Naive, trustful and eager to make new friends they are harshly rejected by the locals, who see them as aliens, with their sheep, their customs, and their reverence to the head of the family, the Grandfather, who makes an almost mythological figure. And only the weird black ram, that seems to appear out of the blue, unites everything as a generalizing metaphor. The ram embodies the attempts to cross the mental gap between Russia and the Caucuses, to overcome the mutual mistrust and hatred that divide the peoples.
